Azure DevOps analysis allow self-signed certificate connection

SonarQube Server / Community Build

  • Using Azure DevOps plugin task SonarQubePrepare@5
  • SonarQube 9.3.0.51899

During Azure DevOps build when setting up SonarQube MSBuild analysis with SonarQubePrepare@5 we are getting following errors:

##[error][SQ] API GET '/api/server/version' failed, error was: {"code":"DEPTH_ZERO_SELF_SIGNED_CERT"}

This one I solved by adding variable NODE_TLS_REJECT_UNAUTHORIZED: 0

And then on re-run another error:

##[error]16:51:17.163  Failed to request and parse 'https://xxx.com/api/server/version': The SSL connection could not be established, see inner exception.
16:51:17.163  Failed to request and parse 'https://xxx.com/api/server/version': The SSL connection could not be established, see inner exception.
##[error]Unhandled exception.

I am aware this is caused by self-signed certificate on the SonarQube instance, we have no plans to change that for now, I am looking for a way to make this work with self-signed cert. Build is running on Azure DevOps hosted agent so configuration options are limited.

Using a Microsoft Azure DevOps Hosted Agent and a self-signed certificate is… pretty brave. Using self-signed certificates for internet-facing services is typically a bad idea

If using self-signed certificates is a requirement, it might be better for you to manage your own build agent where you have full control over things like installing certificates that the system recognizes
